To all whom t may concern; l v

Be it known that I, REGINALD'G. STANDER- wICK'a subject of the King of Great Britlainres iding at Lynn, in the county of Es- Sex, State of Massachusetts, have invented certain new and useful Improvements in Gear and Pulley Devices, of which the following is a specification.

The present invention relates to an improved gear and pulley device particularly --intended for use `in connection with startthe engine is running it is utilized as a gen- V ing, or starting and lighting outfits for-automobiles. i In installing such outfits on cars it is necessary to fasten certain fparts to the engine shaft end, the diameter o which may vary more .or less in different cars even of the same type and make, andthe object of the present invention is to pirovide an improved arrangement of the parts'which are to be fastened tothe engine shaft endso that they may be readily and firmly fixed on a shaft end even though it be slightly over or under size.

For a consideration of what I believe to be novel and my invention, attentionis directed to the accompanying specification and the claims appended thereto.v y In the drawing, Figure 1 is'a diagrammatic view of the forward part of an automobile with a starting and lighting outfit embodying my invention applied thereto;

'F ig. 2 shows 'the end ofthe engine shaft with the parts attached thereto in section; Fig. 3 is a view looking toward the end of the shaft, certain parts beingbroken away for `purposes of illustration; Fig. 4, is a section taken on line 1-J1, Fig. 2; and Fig. 5'

outt, which parts `comprise a pulley 12 from` whichl the Ventilating fan 13 is driven, and a gear wheel 14 which meshes with agear wheel 15 -on the shaft 16 of the starting and lighting dynamo electric, machine 17. It

will be understood tlntnl starting, the machine 17 is utilized as a motor, while when erator. The machine 17 is suitably supported at -the 'rear of' the engine and the forward end of the shaft 16 is supported in a' bearing 18. 19 indicates a sleeve which slips over the end of the shaft 11 and has a flange 20 to which is fastened the gear wheel -14 as by bolts 21. The sleeve thus forms in the pulley 12 is a nut 26 which threads over' the sleeve 19, 27 being an opening in it to receive a tool for screwing it tightly intov position. The inside of the nut is tapered the same as is the sleeve 19. The outer end of the pulley is provided with ratchet teeth 28 to receive the end of the cranking arm 29gin case it is found necessary to crank the engine by hand.

VIn mounting the parts on the end of the engine shaft 11, the'sleeve 19 is slipped over .r

it lnto placeand the pin 23 driven in. The gear wheel 14 is then fastened to the fiange 20. By arranging the gear wheel 14 so that it surrounds the sleeve 19, the structure is materially shortened, and by making it separate from the flange vit does not interfere with'the-insertion ofthe pin 23. The nut 26 carried bypulley12 is next threaded over the end of the sleeve 19 and screwed up until the sleeve is tightly clamped on to the shaft. Since the nut and sleeve are tapered and the sleeve is split, it will be clear thatfthe-parts can be putv on shafts which may.varylfsome what in diameter and whether it be slightly ley and gear wheel arrangement which can' be quickly and readily applied to the shaft yend, and which is compact so as to readily occupy the limited space available for it.

In accordance with-the provisions of the patent statutes, I have described the principle ofoperation of my invention, togethern with the apparatus which I now consider to represent the best embodiment theeo; but I desire to have it understood that 'the apparatus shown is only illustrative and that the invention can be carried out by othergmeans. 4

. By the above described arrangement I provide a simple structure of combined pul- What I claim as Anew and desire to seeure by Letters Patent ofthe UnitedStates, is:-

1. The combination with a shaft4 end of a gearwheel, a split tapered threaded'sleeve forming a hub for the Wheel, said sleevesurrounding the shaft, and `a pulley having a tapered nut formed integral therewith which threads over the tapered sleeve.

2. The combination with a shaft end of a gear Wheel, a s lit ,tapered threaded sleeve forming a hub i or the Wheel, a pin for locking it on the shaft, and a pulley having a tapered nut which threads over the tapered sleeve, the toothed portion of said gear wheel surrounding the sleeve.

3. The combination with an internal c0mbustion engine, a fan, and a dynamo-electric machine, of a combined pulley and gear Wheel on the engine shaft for driving the tric machine respectively,'the same comprising a split tapered threaded sleeve having a flange, a gear wheel lixed to the {ia-nge, a pulley, and a tapered threaded. nut carried thereby and threaded over said s'l'eeve.

4. The combination with a gear Wheel and a pulley, of a split tapered threaded sleeve carried by one of them,- and a tapered threadedl nut carried by the other, said nut being adapted to screw over the sleeve.

5. In an `apparatus of the character described the combination with a shaft of a pulley provided with ratchet teeth, and a tapered threaded nut formed integral there- With, and adapted to be fastened on to the end of said shaft.

In witness whereof, I have hereunto set my hand this eleventh day of April, 1916. REGINALD' G. STANDERWICK.
